General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #110A91, is a deep blue pigment originally derived from the mineral lapis lazuli. Its name comes from the Latin "ultramarinus," meaning "beyond the sea," as lapis lazuli was imported to Europe from mines in Asia. Historically, it was one of the most expensive pigments, often reserved for important commissions, such as the robes of the Virgin Mary in religious paintings. Chemically, synthetic ultramarine is a complex sodium alumino-silicate with sulfur. It is known for its excellent lightfastness and stability, making it a popular choice in various applications, including paints, plastics, and cosmetics. The color falls within the blue-violet spectrum and is often associated with royalty, wisdom, and spirituality.

The color #110A91, also known as Ultramarine, presents several accessibility considerations for web developers. Its dark hue results in a low luminance value, which necessitates careful selection of foreground text colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. White or light-colored text on an Ultramarine background would likely meet these requirements, while darker shades would not. It's crucial to use contrast checking tools to verify compliance. Additionally, developers should avoid relying solely on color to convey information, as users with visual impairments may not be able to differentiate it. Providing alternative cues, such as text labels or icons, is essential for inclusive design. When using Ultramarine, developers should also consider its impact on users with cognitive disabilities. High contrast can sometimes be overwhelming, so a balanced approach is key.
